I'm obviously mean.
Honey sleeps in her bed, in the dining room. Not only is there no heating on through the night, but normally there is no heating on during the day either. We have it on for an hour in the morning and 3 in the evening. With the cold weather, I have been sticking it on during the day for Honey, as we have to leave the door open into the conservatory (from the Dining Room, where Honey's bed is) as otherwise Honey would get no natural light, but it's single glazed with no heating...
She has loads of blankets and my old sleeping bag in her bed, so plenty to snuggle up into, and she seems to do ok!
